abated @man f @liw CARL DIETERICILOF ROSLINDALE, (WEST ROXBURY,)MASSACIIU- .SETTS Letters PatentNo. 88,776, dated April 13, 1869.

The Schedule referred to in these Letters Patent and making part of thesama.

To all persons to 'whom these presents may come:

Be it known that I, CARL DIETERICH, of Roslindale, of the townof W'estRoxbury, of the county 'of Norfolk, and State of Massachusetts, haveinvented a new and useful Improvement in Folding-Chairs; and do herebydeclarethe saine to be fully described in the following specification,and represented in the accompanying drawings, of which- Figure 1 is aside elevation,

Figure 2, a front View,` and Y y Figure 3, a vertical section of one ofmy chairs as unfolded, or with its parts in positions for a person tosit upon the seat.

Figure 4 denotes a front elevation, and

Figure 5, an edge View of the chair in a folded state.

In this chair, the legs and the side-bars of the back are formed by fourlevers, or bars, A A', B B'.

Each of the shorter levers, B or B', covers one of the back levers, A orA', and the two are connected, near the crossing, by a joint-pin, orscrew, et, going through an ear, or short arm, b, projecting forwardfrom the longer or back-bar lever, or from a platec, fastened to theouter side of the same.

The pair of back-bars, or levers A A', is connected by a series of bars,:l e fg, extending between and from one to the other of them, and beingarranged in manner as represented.

The back, h, is secured to the upper two of such bars, and also to thelevers A A.

Furthermore, the pair of shorter levers, B B', is connected by two bars,i k, going from one to the other' of them. p

There is an arm-rest, or iexile band, E, fastened to the upper part ofeach shorter lever, and extended and secured to the longer lever, inmanner as represented.v

`The seat, shown at F, is connected with each of the back-bars, orlevers by means of one of two short bars,

G G, and by screws going through the said bar at its v is screwed intothe seat. The other screw goes through the bar, and is screwed into ltheback-lever. In other words, each link-bar G is to be pivoted both to theseat and to the back-bar.

Theseat is also provided with two hooks, or stops, Z I, to hook, or bearagainst studs m m, (projecting inward from the shorter levers B B,) whenthe chair is in an unfolded state, or its parts in the positions as'indicated in figs. 1, 2, and 3.

Vhen 4the chair is folded, the seat will be turned down into, .or aboutinto, parallelism with the two sets y of levers, A A', B B', and theconnections G G will overlap the studs m m. The ears, or arms b b willcause the shorter levers, when folded, to be in advance of and parallel,or nearly so, with the longer ones, in manner as shown in figs. 4 and 5.They also bring the pivots of the legs nearer the middle of the seatthan would be the ease were 4they to go through the four levers,as invarious other folding-chairs.

The peculiar advantage of the ears b b and the eonnection-bars G G,applied to and arranged with the seat and the two sets of levers, A A',B B', in manner as explained, is, that they enable such parts to befolded together in a better manner than they can be in various otherchairs, and, besides, the connections G G allow the seat to rise upward,while being folded, from a horizontal to a vertical position.

IVhat I claim, in the above-described folding-chair, 1s-

rIhe arrt ngement and combination of the ears b b, and theconnection-bars G G, with the seat and the two sets of levers, the saidbars and ears being connected with the said seat and levers in mannersubstantially as described.
